It is by the Grace of God that we come to Jesus Christ, in repentance towards Salvation; we are sealed for the day of “redemption” of our glorified bodies the Bible tells us. Yet we must choose to walk either in the Holy Spirit, or in the flesh. The Lord will not force us to “yield to the Spirit” in the workings in our lives, as that is up to us to decide. The book of Acts explains to us about the Holy Spirit, and that the “natural mind receives not” the things of God; so that too becomes a choice of our free will – to walk in the Spirit, or the flesh. It has taken me a long time to understand this rift between the “spiritual” brethren, and the “natural” ones!
